“…1), we have embedded several of these sensors in a single lap adhesive joint (SLJ). A SLJ is a simple structure for which the shear stress distribution in the adhesive layer is well known and can be described by analytical models [42]. The analysis of Goland-Reissner [43] is a classic two-dimensional linear elastic method to analyze SLJs and to determine not only the shear stress in the bond layer, but also the peel stress that is induced by the bending moment caused by eccentric loading of the joint.…”

Abstract:We demonstrate shear stress sensing with a Bragg grating-based microstructured optical fiber sensor embedded in a single lap adhesive joint. We achieved an unprecedented shear stress sensitivity of 59.8 pm/MPa when the joint is loaded in tension. This corresponds to a shear strain sensitivity of 0.01 pm/µε. We verified these results with 2D and 3D finite element modeling. A comparative FEM study with conventional highly birefringent side-hole and bow-tie fibers shows that our dedicated fiber design yields a fourfold sensitivity improvement.

“…It can be seen that declining failure loads with increasing adhesive layer thicknesses are predicted and the results of the present model are in a very good agreement with the experimental and numerical results. Classical approaches consisting of either a stress or energy criterion cannot cover this effect correctly [7]. Moreover, in Fig.…”

In this work, crack initiation in adhesive lap joints of arbitrary joint configuration is studied by means of a finite fracture mechanics approach. The analysis is based on a general stress solution for adhesive joints combined with a coupled stress and energy criterion. The instantaneous formation of a crack of finite size is predicted if a stress and energy criterion are satisfied simultaneously. The closed-form analytical solution of the stress field allows for an efficient evaluation of the crack initiation load and corresponding finite crack length. A comparison to experimental results from literature and to numerical results obtained with a cohesive zone model approach shows a good agreement.

Abstract. The purpose of this work is to determine the failure criterion evolution of assembly bonded with a strain rate dependent adhesive. A new modified ARCAN device is then designed to obtain the average stress at failure under different loading angles and for strain up to 350 s −1 . Tests are performed on a hydraulic jack machine and a Digital Image Correlation measurement is used to control the opening and the sliding displacements of the two substrates.
